To all whom it may concern;

Be it known that I, THOMAS LoURrM, a citizen of the United States,residing at the city of Battle Creek, county of Calhoun, State ofMichigan, have invented certain new and useful Improvements in Sieves,of Which the following is a specification.

This invention relates to improvements in sieves.

My improved sieve is particularly designed by me as a riddle for moldersuse, although it possesses features which render it valuable for use inother relations.

The main object of this invention is to provide an improved sieve whichis very simple and economical in structure and at the same time verystrong and durable and one from which the screen may be readily removedor inserted therein.

Further objects and objects relating to.

a line corresponding to line 3 3 of Fig. 2, showing structural details.Fig. 4 is a detail sectional view taken on a line corresponding to line4 4 of Fig. 2, showing structural details. Fig. 5 is a detail plan viewshowing the joints in the rim.

Referring to the drawings, the sieve frame or rim A is formed of a stripof sheet metal and is preferably rim or band like in form. The ends ofthe strip are overlap ed and detachably secured together by bol ts C,which are arranged through the overlapping portions thereof. The edgesof the rim are rolled outwardly to form beads which embrace the rods AA. The ends of the rods A A project at one end of the rim and formdowels. 'These rods do not extend quite to the opposite end of thebeads, the beads forming sockets to receive the projecting ends of therods or dowels. By this arrange- -ment the ends of the rim are connectedtogether, and when the bolts C are in place a very secure and rigidjoint is obtained. It is evident that the parts can be assembled veryquickly and easily.

The rim A is preferably provided with suitable annular corrugations tostrengthen the same, as is illustrated in the drawings. Toward thebottom of the rim is an annular groove-like seat B for the screen. Theedges of the screen B are rolled over and secured to the ringB, thediameter of which is such as to allow it to rest in the seat B when theends of the rim are secured together. Below the screen-seat is a pair ofradially-arranged brace-rods a.

In inserting the screen it is only necessary -to free the ends of therim and drop the screen into its seat and again secure the ends of therim together. It is evident that this can be done quickly and easily.This structure is of very great advantage, as for molders use thescreens are likely to become gummed up or clogged, and it is often necessary to use several screens of different mesh. If desired, one rim orframe can be made to answer for several screens. The screen is sosupported by the ring B that, if desired, the same can be placed in thefire a short time for the purpose of cleaning. This will be found to bea very great advantage as a timesaver. Also the structure is veryeconomical on account of its structural simplicity and durability andthe convenience with which it may be manipulated.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a sieve, the combinationof a frame or a rim formed of a strip ofsheet metal, having its ends overlapped and its edges formed into beadsrods arranged in said beads and projecting therefrom at one end to formdowels, and the other end of said beads forming sockets to receive thesame a screen-seat in said rim; a screen a wire ring to which the edgesof said screen are secured; and bolts arranged through the overlappedends of said rim whereby the same are detachably secured together, forthe purpose specified.

2. In a sieve, the combination of a frame or a rim formed of a strip ofsheet metal, having its ends overlapped, one end of said rim havingdowel-pins thereon and the other, sockets to receive said dowel-pins; anannular groove-like screen-seat formed in said rim fa screen; a wirering to which the edges the edges of said screen are secured; and boltsof said screen are secured; and bolts arranged arranged through theoverlapped ends of through the overlapped ends of said rim said rimwhereby the same are detachably whereby the same are detachably securedtosecured together, for the purpose specified. gether, for the purposespecified. In witness whereof I have hereunto set my 3. 111 a sieve, thecombination of a frame hand and seal in the presence of two witor a rimformed of a strip of sheet metal, havnesses.
